Fig. 7 is the 1st timing diagram of wireless terminal.M shown in Fig. 7 indicates the timing of wireless terminal 12 wirelessly measured.P table
Show the timing of the monitoring of the paging signal of wireless terminal 12.
In the example of Fig. 7, before and after the event of detection application layer, the timing of m, p are different.Such as taking according to ammeter etc.
Event is generated with report, exception reporting.
Wireless terminal 12 for example uses in order to reduce power consumption and recycles long long DRX circulation than common DRX.
Here, the previous measured value wirelessly measured is that ' DRX recycles wirelessly measuring for/2 ' interval at least having
Sample is averaged and is calculated.Thus, for example the interval wirelessly measured extends shown in the arrow A3 of Fig. 1, wirelessly measure
Measurement accuracy deterioration.
In contrast, wireless terminal 12 as in the past, implements 1 wireless measurement with the interval of at least DRX.Therefore, exist
It can implement repeatedly wireless measurement in the section of some DRX.But with ' interval of long DRX circulation/n ' (n > 2) is surveyed to wireless
Fixed sample value is filtered, and calculates measured value.Therefore, wireless terminal 12 is wirelessly surveyed with the interval of ' X ' shown in Fig. 7
It is fixed.
In addition, wireless terminal 12 for example averages 2 wireless measurements, the measured value wirelessly measured is calculated.For example,
In long DRX circulation before the event generation shown in Fig. 7 of wireless terminal 12, in the m and the m on right side in left side, this 2 timings are used
The sample value wirelessly measured calculates measured value.In addition, in the long DRX circulation of wireless terminal 12 after an event occurs, in left number the 1st
A m and the 2nd m calculates measured value using the sample value wirelessly measured.In addition, wireless terminal 12 is in the 3rd m and the 4th m of left number
Measured value is calculated using the sample value wirelessly measured.
In addition, after an event occurs, before occurring compared to event, the number wirelessly measured in long DRX circulation increases.
For example, in Fig. 7, before event generation in, the number wirelessly measured is 2 times, but is become 4 times after an event occurs.This is
Because can be carried out to cell appropriate pre- by increasing the number wirelessly measured, improving the evaluation precision wirelessly measured
It accounts for, event information is suitably notified to base station.In addition, wireless measurement of the wireless terminal 12 after being occurred by event is judged as
In the case where can not being connect with previous cell, implements cell selection, attempt the detection of new cell.In addition, wireless terminal 12

The interval of line measurement is shortened, and interval Y is become.That is, the frequency that Fig. 8 compared to Fig. 7, is wirelessly measured increases.Wireless terminal 12 as a result,
Power consumption rise compared to Fig. 7, still, between being averaged in the measured value that wirelessly measures calculates to each sample
Every shortening, therefore measurement accuracy improves.
It is not that the shorter equalization interval the better but in the measured value wirelessly measured calculates.It was spaced in equalization
